crystal report

hi,
i am using crystal report to prepare reports. my database is in oracle 9i. i am using vb.net 2003. after creating crystal report whenever i am going to view the report in button click event it is asking me to give login id and password. for each and every report and for each time i am loading the report it is asking me to do so. can any one kindly help me, so that it wont ask me again and again. is there any process to do so. Thanks in advance. its very urgent. can any one please guide me to do so.
